From 1ec33e22b8bd10136c415c6c1b924bf32057354d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Thu, 18 May 2023 22:08:23 +0200 Subject: [PATCH] soundwire: amd: Improve error message in remove callback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Returning an error code in the remove callback yields to an error message remove callback returned a non-zero value. This will be ignored. After that the device is removed anyhow. Improve the error message to at least say what the actual problem is. While touching that code, convert the driver to the .remove_new() callback which returns no value with the same effect as returning zero in a .remove() callback. As the return value is ignored by the core the only effect of this patch is to improve the error message. (And the motivating effect is that there is one less driver using .remove().)
